Information about RF Receivers

RF receivers are electronic devices that separate radio signals from one another and convert specific signals into audio, video, or data formats. RF receivers use an antenna to receive transmitted radio signals and a tuner to separate a specific signal from all of the other signals that the antenna receives. Detectors or demodulators then extract information that was encoded before transmission. There are several ways to decode or modulate this information, including amplitude modulation (AM) and frequency modulation (FM). Radio techniques limit localized interference and noise. With direct sequence spread spectrum, signals are spread over a large band by multiplexing the signal with a code or signature that modulates each bit. With frequency hopping spread spectrum, signals move through a narrow set of channels in a sequential, cyclical, and predetermined pattern.

RF Modules

RF modules are partially finished circuits that can be incorporated into larger designs.

RF Transceivers

RF transceivers are electronic devices that receive and demodulate an RF signal, then modulate and transmit a new signal.

RF Transmitters

RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal.

Telemetry Receivers and Telemetry Transmitters

Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication.
